SCISSORS OR SHEARS.

SPECIFICATION forming part of Letters Patent No. 453,908, dated June 9,1891. Application filed October 29, 1890. Serial No. 369,679. (Nomodel.)

To all whom it may concern:

Be it known that I, JULIUS LANGENBERG, manufacturer, of Ohligs, in theKingdom of Prussia and German Empire, have invented new and usefulImprovements in Scissors or Shears, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to scissors or shears, and has for its object theproviding of means to increase their efficiency in cutting.

In order that my invention may be the better understood, I now proceedto describe the same with reference to the accompanying drawings, and tothe letters marked thereon.

Like letters refer to like parts throughout the figures.

Figure 1 shows my improved scissors when closed. Fig. 2 shows the samescissors open, as seen from the opposite side. Fig. 3 shows thecommencement of the inner side of the blade I) with the hole for the pind. Fig. at shows the arrangement of the pin (Z through the part b, andthe method of screwing the spring 6, connected to the pin (Z on the partb at f.

Somewhat below the pin Ct another pin d is arranged on the upper part bof the scissors or shears, which acts on the lower part 0 through a holeby means of a spring-pressure. By this means the two blades are pressedagainst each other automatically without using any handpressure duringcutting, even if the pin should become somewhat loosened by the screwbeing unscrewed or worn. This insures the blades cutting the materialduring the whole cutting movement from the point where the edges meettoward the ends.

In ordinary scissors, as shown in the draw ings, the pin (1 need onlyprotrude very little through the part I), (see Fig. 4,) while in largescissors or shears, the blades of which are not so close together, thepin must be correspondingly longer. The extent to which the end of thepin d protrudes beyond the inner face of the part 1) depends upon theamount of space between the two blades, while the pressure of the pinagainst the blade 0 is regulated by the screw f. When the screw isturned to the right its head will bear on the spring e and cause it topress the pin (Z inward against the blade 0, and when .turned to theleft the head will cease to bear on the spring, which will then exert nopressure on the pin. The latter arrangement allows of the pin (Z beingplaced out of action.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

The scissors comprising the pivoted blades and a spring-pressed pinprotruding through one of the blades so as to impinge upon the other,substantially as described.
